In this paper we present work on exploiting visual temporal masking phenomenon applied to video compression. Our results show that it is possible to reduce bitrate of the compressed video sequence without affecting subjective quality and quality of experience (perceptually lossless). The principles we present here are applicable to all modern hybrid coding systems and can be implemented seamlessly with video delivery platforms. Results show up to 6% of additional savings when implemented on top of the state of the art encoder.

Telematics services are predicted to spread to many more consumers with the increased availability of free telematics smartphone applications. In these telematics services, servers and consumer devices such as smartphones and car navigation terminals have to communicate large amounts of various types of data by uplink and downlink. Finding methods to decrease the data size for communication is one of the most significant issues in this field because of the cost for consumers and service providers. In this paper, we propose a new data compression method for telematics, which deletes redundant data and applies an appropriate compression method for a situation. Moreover, we evaluated our method with the probe data defined by ISO22837 and report positive results.

The proposed SUN OFDM-based RF CMOS transceiver, with replacement of ZigBee, can be used as not only an energy saving intelligent green home, which is related to Smart Grid, but also an universal remote controller, a Building Automation, and so on. With our proposed SUN OFDM RF transceiver, wireless connectivity among CEs (Consumer Electronics) devices and electric meters can save electronic energy and make lives more comfortable. The proposed RF transceiver consists of a RF front-end, a TX BBA (Base Band Analog), a RX BBA, and a PLL. Re-using of a LC resonator in the RF front-end can reduce the chip size of RF transceiver, DC power consumption, and the cost. The proposed RF transceiver is implemented in a 0.18-μm CMOS technology and consumes 37-mA in TX and 38-mA in RX mode from a 1.8-V supply voltage. In addition, with a fabricated RF transceiver chip, we have succeeded a public demonstration.

We propose pointing gesture-based large display interaction using a depth camera. A user interacts with applications for large display by using pointing gestures with the barehand. The calibration between large display and depth camera can be automatically performed by using RGB-D camera. The experimental result shows that the pointing accuracy is 96.2%. We demonstrate the puzzle game application using the proposed system.

In this paper, received signals and the channel information are transmitted by using one-way or two-way communication. Maximum ratio combining scheme are performed in the own terminal using the exchanged channel information. The error rate performance can be improved by using multiple receiving terminals in the One-Segment Service.

We propose an efficient single reference superresolution system based on the discrete wavelet transform. We assume that the low-resolution image to be enhanced is the low-frequency subband of the high-resolution image to be reconstructed. We design a support vector machine synthesizing the high-frequency subband based on the inter-subband correlation of the directional edges. Experimental results of sample images show that the proposed system offers improvements in terms of both measured distortion and subjective appearance.

Remote monitoring of heart disease patients has been shown to be effective for diagnosis and detection of arrhythmias. We propose a remote cardiac monitoring system for preventive care by developing a decision support system with personalized parameters and an algorithm to predict forthcoming paroxysmal atrial fibrillations. The system consists of several physiological measuring devices, mobile gateways, point-of-care devices, and a monitoring server. The proposed prediction algorithm shows 87.5% accuracy.

In this paper, we propose a novel V2V transmission scheme, namely S3-RNC (Shuffled Scattered Symbol-level Random Network Coding), for Mobile Content Distribution (MCD) between communication pairs traveling on opposite directions. To cope with the Doppler Effect caused by extremely high relative velocity, symbol-level random network coding (RNC) with shuffling (interleaving) and scattering is used in our proposed scheme. As the second step, receivers, moving together as a cluster, cooperatively relay their received S3-RNC coded blocks, in order to maximize the probability of successful decoding. Our simulation results show that S3-RNC improves throughput performance significantly in high mobility environment. By utilizing S3-RNC, consumer vehicular communication devices are able to provide a lot of useful information to vehicular users.
在本文中，我们提出了一种新的V2V传输方案，即S3-RNC (Shuffled Scattered Symbol-level Random Network Coding)，用于移动内容分发(MCD)。为了应对极高的相对速度所带来的多普勒效应，我们提出的方案采用了带洗牌(交织)和散射的符号级随机网络编码(RNC)。第二步，接收器作为一个集群一起移动，合作中继接收到的S3-RNC编码块，以最大限度地提高解码成功的概率。仿真结果表明，S3-RNC在高移动性环境下显著提高了吞吐量性能。通过利用S3-RNC，消费级车载通信设备能够为车载用户提供大量有用的信息。

This paper presents a new intra prediction technique for HEVC, which is next-generation video coding standard that has collaboratively been developed by ISO/MPEG and ITU-T/VCEG. On intra coding for HEVC, extension of MPEG4-AVC/H.264-like intra prediction scheme has been studied. In this conventional scheme, the prediction block is generated by simply copying adjacent reference samples, interpolating the reference samples toward prediction direction or averaging the reference samples. Thus, signal discontinuity between prediction block and adjacent reconstructed blocks could occur, which causes loss of coding efficiency of residual signal. In this paper, we propose an adaptive filtering scheme for intra prediction samples generated by either DC or directional prediction that solves the above issue. According to our evaluation, the proposed scheme achieves approximately 0.6% bitrate savings on average compared to the conventional AVC-style intra coding.
